Uradome Coast Island Cruise

The Uradome coast is fifteen kilometres of granite worked by the Sea of Japan into caves, arches, stacks and inlets, with water clear enough that the bottom is visible several metres down. It is a national Place of Scenic Beauty and Natural Monument and part of the San'in Kaigan UNESCO Global Geopark. Most of the best of it cannot be seen from land.

The island-circuit boats run from Ajiro port between March and November on an hourly schedule, taking about forty minutes to work through the inlets and past the arches. A smaller boat gets into places the main vessels cannot. Sea kayaking operators work the same water in summer, which is the closest way to see it. The clarity is the thing people remember; on a calm day the boats appear to be floating on air.
